It delivers ±4.0 A peak output current, 150 ns max propagation delay, ±35 kV/µs common-mode transient immunity, and operates from -40 °C to +125 °C in a 6-pin SO6L package.

For engineers reviewing the TLP5751H(D4TP4,E) datasheet, TLP5751H(D4TP4,E) pinout, TLP5751H(D4TP4,E) application, or TLP5751H(D4TP4,E) equivalent, this device serves as a rail-to-rail, buffer-type isolator optimized for IGBT/MOSFET gate drive in safety-certified AC inverter systems requiring UL, VDE, and CQC compliance.

Technical Context

The TLP5751H(D4TP4,E) integrates an infrared LED input stage with a monolithic photo-IC detector featuring a Faraday shield and totem-pole output stage. Its internal architecture enables direct gate drive without external buffers while maintaining guaranteed isolation performance up to 125 °C ambient.

This variant implements the EN IEC 60747-5-5 Option (D4), satisfying reinforced insulation requirements including minimum creepage/clearance of 8.0 mm and insulation thickness ≥0.4 mm. It requires a 1 µF bypass capacitor between VCC (Pin 6) and GND (Pin 4) for stable high-speed switching.

FAQ

What safety certifications does the TLP5751H(D4TP4,E) hold?

The TLP5751H(D4TP4,E) is UL-recognized (UL 1577, File No. E67349), cUL-recognized (CSA 5A File No. E67349), VDE-approved to EN IEC 60747-5-5 and EN IEC 62368-1 (via Option D4), and CQC-approved to GB4943.1. The "D4" suffix explicitly denotes qualification to the reinforced insulation requirements of EN IEC 60747-5-5, including creepage/clearance ≥8.0 mm and insulation thickness ≥0.4 mm. These certifications apply directly to the TLP5751H(D4TP4,E) part number as shipped.

Does the TLP5751H(D4TP4,E) require an external bypass capacitor?

Yes, a 1 µF ceramic bypass capacitor must be placed between Pin 6 (VCC) and Pin 4 (GND) of the TLP5751H(D4TP4,E), located within 1 cm of the pins. This capacitor stabilizes the internal photo-IC's high-gain amplifier and is mandatory for proper switching behavior - omission causes erratic output or failure to switch. The requirement is specified in Toshiba's official datasheet Section 6 (Internal Circuit Note) and Section 9 (Recommended Operating Conditions).

What is the maximum operating temperature for the TLP5751H(D4TP4,E)?

The TLP5751H(D4TP4,E) is rated for continuous operation from -40 °C to +110 °C ambient temperature. While the broader TLP575xH family includes variants like TLP5754H qualified to +125 °C, the TLP5751H(D4TP4,E) datasheet specifies +110 °C as the maximum operating temperature (Topr). This limit applies across all electrical parameters and must be respected in thermal design - exceeding it risks parametric shift or reliability degradation.

Can the TLP5751H(D4TP4,E) drive both IGBTs and MOSFETs directly?

Yes, the TLP5751H(D4TP4,E) can directly drive both IGBTs and MOSFETs thanks to its ±4.0 A peak output current and rail-to-rail totem-pole output stage. Its 15–30 V supply range aligns with standard gate driver voltages, and the 150 ns max propagation delay supports switching frequencies up to 50 kHz. However, gate resistance selection must be optimized per device - e.g., 10 Ω for 1200 V IGBTs, 2.2–4.7 Ω for 100 V MOSFETs - to balance switching speed and ringing, as confirmed by Toshiba's application guidance for the TLP5751H(D4TP4,E).

What is the meaning of "(D4TP4,E)" in the TLP5751H(D4TP4,E) part number?

In TLP5751H(D4TP4,E), "D4" indicates qualification to EN IEC 60747-5-5 reinforced insulation; "TP4" denotes tape-and-reel packaging (1500 pcs/reel); and "E" signifies RoHS-compliant, lead-free construction. This full suffix defines a specific, orderable variant - not a generic family designation. The base type TLP5751H remains unchanged; the suffix confirms safety certification, packaging format, and environmental compliance for the exact TLP5751H(D4TP4,E) unit shipped.
